1. OpenGL will be slower, but is the load on the GPU only?
2. All glitches affecting OpenGL in Windows and Mac OS X are also present in Linux, correct?

Quote:I'm currently running Dolphin in a 30-day trial of Windows 7 x64 and it works beautifully on my new PC. The problem is... it's a trial. It's gonna end eventually, and Windows is not cheap. I'm trying to decide whether I should extend my trial (there is a legal way to do this that Windows provides for free) so that I can buy Windows 8 later or switch to Linux (Xubuntu 64 bit). Linux only has one backend though (OpenGL), which is slower than Direct3D9/11 and sometimes has bugs that aren't found in D3D9/11. I want to know if I can possibly get full speed in all of the following games (pc specs in sig) with at least 2x IR on Linux:

I'll quote the new FAQ for you: "Dolphin will run on Windows (>= XP), Linux and OS X (>= Snow Leopard). Generally speaking, you will run games faster and with less issues on Windows over all others. Windows 7 x64 is recommended."

Without getting too detailed, if at all possible, stay with Windows 7. Anything else would be a downgrade one way or the other.

I was using windows 7 RC a year past the deadline without any issues. All I had to do was change my system clock in the bios setup to a year earlier. I wonder if that trick still works.

No. It's complicated, I'll just leave it at that.

I should point out there that the openGL backend generally runs a lot better on linux than it does on windows. You should in fact be able to attain similar performance to using the d3d9 backend on windows.

No. Most of the major openGL bugs on MAC OSX shouldn't occur on a windows build using the openGL backend because they are caused by driver issues that are only present in the MACOSX drivers. Most linux video drivers these days are pretty good so you shouldn't have many issues with "glitches".
